Swarm intelligence techniques are offers an optimal or suboptimal solution to multidimensional rough objective functions. This work proposed the Fractional Order PI controller to control the level of horizontal cylindrical tank(HCT). Craziness Particle Swarm Optimization technique is used for designing PI and Fractional Order PI controllers that give better performance than their integer order controller. The response time, steady state error, load disturbance, and control valve action of the tank system are tested and compared with the conventional controller. The control valve action of the FOPI controller has operation high frequency than the conventional PI controller so the water level in horizontal tank is smoothly constant. Results show that this design method can effectively tune the parameters of the fractional order controller.
